readily withoutpermitting dirt to enter within the wheel about the-axle,the novelty lying essentially in the means whereby the entrance of dirtis avoided.

lVith the above and other obj ects' in view which will appear as thedescription proceeds, the invention resides 1n the comblnation andarrangement of parts and 1n the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the vention' herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 shows the invention in frontelevation;

Fig. 2 is a rear elevation;

Fig. 3 is a side elevation;

Fig. 4 is a longitudinal section on the line ll of Fig. 1;

Fig. 5 is a section on the line 5-5 of Fig. 4; and

Fig. 6 is a perspective view showing the upper retaining member.

In the accompanying drawings, the numeral 1 indicates a standard of thekind which is commonly assembled with the forward end of a plow beam,and is adapted to carry a gage wheel. The standard 1 is provided with anoutwardly projecting axle 2. The invention includes a wheel 3 includingan outer hub a closed at its outer end as in dicated at 5, and providedwith a peripheral oil hole 6. A closure for the oil hole is provided,the closure 10 if desired being in the form of a screw plug. The wheel 3includes a tread rim 7 and an inner hub 8 having a circumscribing rib 9.The axle 2 is received in the hubs at and 8.

The invention comprises an upper retainer 11 and a lower retainer 12applied to the inner face of the standard 1 and having abutting ends 14provided with cooperating notches 15 receiving the inner hub 8 forSpecification of Letters Patent.

rotation. The retainers 11 and 12 are equipped with cooperating recesses1 6 receiving for rotation the rib 9 onthe hub 8. The upper edge of theupper retainer 11 is pointed to form adirt deflector 1 7. Bolts 18extend through the retainers 12 and 11 andthrough the standard 1, theheads of the bolts 18 being countersunk, if desired, into the retainers.Nuts-19 are threaded onto the rear end of the bolts and engage the rearface of the standard 1. The bolts may be described as studs carried bythe retainers 11 and 12. If desired; the upper retainer 11 may beslightly wider than'the lower retainer 12, fora purpose whichwill'be'made manifest hereinafter, attention being directed to the pointat which the reference character 20 is applied.

In practical operation, the'closure 10 may be removed from'the oil hole6; to permit a lubrication of the axle 2 in the usual man- Especialattention is directed to the finding its way within the wheel 3 aboutthe axle 2. Under this heading, and with the above mentioned object inview, it is to be observed that the outer hub 4 is closed as shown at 5at its outer end, and consequently dirt cannot find its way within thewheel at this point. Further, the tread 7 overhangs the oil hole 6, anddirt on the tread rim cannot drop into the oil hole or about the oilhole. Owing to the fact that the inner hub 8 is provided with thecircumscribing rib 9 which is received for rotation in the recesses 16of the retainers 11 and 12, no dirt can enter within the wheel adjacentthe inner hub. Since the ends of the retainers 11 and 12 abut in closerelation, as shown at 14, it will be difficult for dirt to find itswaybetween the abutting ends of the retainers. By tightening up the nuts19, the retainers 11 and 12 may be drawn closely against the standard 1,and consequently, dirt cannot find its way between the retainers and thestandard. Dirt deposited on top of the upper retainer 11 will be carriedlaterally, owing to the fact that the upper retainer embodies the dirtdeflector 17. In this connection, noting the point at which thereference character 20 is applied, and recalling that the upper retainer11 is slightly wider than the lower retainer 12, it will be understoodthat as dirt slides down the vertical edges of the upper retainer 11,the dirt will not be caught upon the upper end of the lower retainer 12.

From the foregoing it will be obvious that in this application there isdisclosed a novel combination of elements cooperating to produce asingle result, namely, to prevent the passage of dirt within the wheel 3about the axle 2.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, a standard having an outwardly projecting axle;a wheel including an outer hub closed at its outer end and provided witha peripheral oil hole, a tread rim overhanging the oil hole, and aninner hub having a circumscribing rib, the axle being received in bothhubs; a closure for the oil hole; an upper retainer and a lower retainerapplied to the inner face of the standard and having abutting endsprovided with cooperating notches receiving the inner hub, the retainershaving coacting recesses receiving the rib of the inner hub forrotation, the upper end of the upper retainer being pointed to form adirt deflector; studs carried by the retainers and projecting throughthe standard; and clamping devices on the studs and engaging thestandard to bind the retainers closely against the standard.

standard having an outwardly projecting axle; a wheel including an outerhub closed at its outer end and provided with a peripheral oil hole, atread rim overhanging the oil hole, and an inner hub having acircumscribing rib, the'axle being received in both hubs; a closure forthe oil hole; an up per retainer and a lower retainer applied to theinner face of the standard and having abutting ends provided withcooperating notches receiving the inner hub, the retainers havingcoacting recesses receiving the rib of the inner hub for rotation, theupper end of the upper retainer being pointed to form a dirt deflector,and the upper retainer being wider than the lower retainer, measured ina direction at right angles to the standard and parallel to the wheel;studs carried by the retainers and projecting through the standard; andclamping devices on the studs and coacting with the standard to bind there tainers closely against the standard.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
